Gnulib module: readdir

Portability problems fixed by Gnulib:

This function is missing on some platforms:
|
|
MSVC 14.
|
|
@item
|
|
On platforms where @code{off_t} is a 32-bit type, this function may not
|
|
work correctly on huge directories larger than 2 GB. Also, on platforms
|
|
where @code{ino_t} is a 32-bit type, this function may report inode numbers
|
|
incorrectly. (Cf. @code{AC_SYS_LARGEFILE}.)

Portability problems not fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
Although POSIX places no restrictions on @code{d_ino} values, some
|
|
older systems are rumored to return @code{d_ino} values equal to zero
|
|
for directory entries that do not really exist. Although Gnulib
|
|
formerly attempted to cater to these older systems, this caused
|
|
misbehavior on standard systems and so Gnulib does not attempt to
|
|
cater to them any more. If you know of any problems caused by this,
|
|
please send a bug report.
